Corrugated metal pipe (CMP) is the “go-to” material for most stormwater detention and infiltration projects. A wide range of gages, corrugations, and diameters

Early in my stormwater monitoring days, even though I had access to high-end automated samplers, flow meters, and data loggers, transferring said data required

To understand the physical and biological processes in a high-rate biofiltration system, it’s necessary to look at how each system component contributes to

High-rate biofiltration differs from traditional bioretention in that it has been optimized for high volume/flow treatment and high pollutant removal.

As previously discussed in our “Construction Cover vs. Post Construction Cover” blog post, the total cover required for a system is the combination of the

If you’ve ever been confused about the cover requirements over underground detention systems, you’re not alone. Why do the requirements change during

High-flow bioretention systems target the removal of suspended solids, total and dissolved nutrients and metals, oil and grease, trash, and debris. Components

High rate biofiltration continues to gain acceptance within the regulatory and engineering community as an acceptable alternative to traditional bioretention.

“One’s company, two’s a crowd, and three’s a party” may not exactly apply to manufactured treatment devices (MTDs), but hopefully, this post can offer some

ASTM International (ASTM) has been a recognized leader in consensus standard development by many different industries for more than 100 years now. ASTM’s
